                                   ISSUE PRICE

1.1      The issue price for the Preferred Stock, Series B shall be determined 
by resolution of the board of directors of the Corporation.

                                    DIVIDENDS

2.1      Payment of Dividends

         The holders of the Preferred Stock, Series B shall be entitled to
receive, and the Corporation shall pay thereon, as and when declared by the
board of directors out of monies properly applicable to the payment of
dividends, fixed cumulative preferential cash dividends at the rate of 5% per
share per annum (the "Dividend Payment") on the amount paid-up thereon payable
in arrears on December 31 of each year (the "Dividend Payment Date"). Dividends
on the Preferred Stock, Series B shall accrue from and including the date of
issuance. Cheques of the Corporation or its dividend paying agent payable at par
at a chartered bank or trust company shall be issued in respect of such
dividends to the holders of the Preferred Stock, Series B entitled thereto. The
mailing of such cheques shall satisfy and discharge all liability for the
dividends represented thereby, unless the cheques are not paid on due
presentation. If on any Dividend Payment Date, the dividends payable on such
date are not paid in full on all of the Preferred Stock, Series B then issued
and outstanding, the dividends or the unpaid part thereof shall be paid on a
subsequent date or dates as determined by the board of directors. The holders of
the Preferred Stock, Series B shall not be entitled to any dividends other than
or in excess of the cash dividends provided for herein. A dividend which is
represented by a cheque which has not been presented for payment within six
years after it was issued shall be forfeited to the Corporation.

                  holders of Preferred Stock, Series B on the liquidation,
                  dissolution or winding-up of the Corporation, whether
                  voluntary or involuntary, or on any other distribution of
                  assets of the Corporation among its shareholders for the
                  purpose of winding up its affairs,

shall be equal to the amount (rounded to the nearest 1/100th of 1 cent)
calculated by multiplying the Dividend Payment by a fraction of which the
numerator is the number of days during the year




   8



that the share has been outstanding (including the date of issuance or the first
day of the year as well as the Dividend Payment Date or date of redemption,
purchase, or distribution of assets, as applicable) and the denominator is 365.

2.3      Interest Payment

         The holders of the Preferred Stock, Series B shall be entitled to
receive, as provided herein, an amount equivalent to interest at the rate of 8%
per annum on the amount of all Dividend Payments not paid on their respective
Dividend Payment Dates and which remain outstanding from time to time, which
shall be compounded annually on each Dividend Payment Date (the "Interest
Amount").

                                    SECTION 3
                             REDEMPTION AND PURCHASE

         (a)       Subject to Section 6, the Corporation may at its option 
                   redeem at any time all or from time to time any number of the
                   outstanding Preferred Stock, Series B on payment of the
                   Redemption Price as provided in Section 3.3.

         (b)       If less than all of the outstanding Preferred Stock, Series B
                   are to be redeemed, the shares to be redeemed shall be
                   selected by lot, in single shares or in units of 10 shares or
                   less, or pro rata (disregarding fractions) as the board of
                   directors or a committee thereof in its sole discretion shall
                   by resolution determine.

any Interest Amount applicable thereto and a redemption premium of 10% of the 
amount paid-up thereon.

3.4      Redemption Procedure

         (a)       Notice of redemption (the "Redemption Notice") of the
                   Preferred Stock, Series B shall be given by the Corporation

                   to each holder of any Preferred Stock, Series B to be

                   Redemption Notice to one or more of




   9



                  such holders shall not affect the validity of such redemption.
                  The Redemption Notice shall set out the Redemption Price, the
                  date fixed for redemption, the place of redemption and, in the
                  case of partial redemption, the number of the holder's shares
                  to be redeemed.

         (b)      On and after the date fixed for redemption, the Corporation
                  shall pay or cause to be paid the Redemption Price to or to
                  the order of the holders of the Preferred Stock, Series B
                  redeemed on presentation and surrender, at the place of
                  redemption, of the respective certificates representing such
                  shares, and the holders of the Preferred Stock, Series B
                  called for redemption shall cease to be entitled to dividends
                  or to exercise any of the rights of holders in respect
                  thereof, unless payment of the Redemption Price shall not be
                  made in accordance with the foregoing provisions, in which
                  case the rights and privileges of the holders shall remain
                  unimpaired.

         (c)      The Corporation shall have the right at any time after mailing
                  the Redemption Notice to deposit the Redemption Price of the
                  shares thereby called for redemption, or such part thereof as
                  at the time of deposit has not been claimed by the
                  shareholders entitled thereto, in a special account with a
                  chartered bank or trust company for the holders of such
                  shares, and upon the deposit being made or upon the date fixed
                  for redemption, whichever is the earlier, the Preferred Stock,
                  Series B in respect of which the deposit shall have been made
                  shall be deemed to be redeemed and the rights of each holder
                  thereof shall be limited to receiving, without interest, his
                  proportionate part of the Redemption Price so deposited upon
                  presentation and surrender of the certificates representing
                  his shares so redeemed.

         (d)      If less than all the Preferred Stock, Series B represented by

firm holding membership on a stock exchange) or pursuant to tenders received by
the Corporation upon an invitation for tenders addressed to all holders of the
Preferred Stock, Series B, at a price per share not exceeding the Redemption
Price plus costs of purchase. If, upon any invitation for tenders, the
Corporation receives tenders for Preferred Stock, Series B at the same price in

                  or other communication to one or more holders of the Preferred
                  Stock, Series B shall not affect the validity of the notices,
